USB

The Axe-Fx II connects to a computer through USB (or MIDI). It's described in this part of the manual.

USB support is Audio Class 2.0 compliant. The USB interface supports:

1. Editing / remote control via Axe-Edit (no need for a MIDI interface)
2. Audio communication (no need for an audio interface)
3. Use as an exclusive USB-to-MIDI interface for other products (in the I/O > MIDI menu set "USB ADAPTER MODE" to ON).

Editing and recording can be done simultaneously.

Drivers for Mac and PC which add support for the USB functionality are available for download here.

Notes:

• If you're monitoring audio through the Axe-Fx II itself there's no latency. When monitoring the audio signal through the computer, the latency is determined by the host computer capabilities.
• If you experience noise (high freq. buzzing) when using an USB connection it may be a ground loop. Cliff: "The USB spec calls for grounding the cable at both ends (mistake). This can create a ground loop. Make sure everything is plugged into the same outlet strip." Source
• If you're recording with an application which use the system selected input (all 4 channels), you will end up with a recording that contains the dry tracks also. The Axe-Fx II currently doesn't let the user mute the dry tracks. Source
• The Axe-Fx II cannot connect to a USB stick. Source
